Keshava Munegowda e2e49d5719 mfd: Fix the omap-usb-host clock API usage on usbhs_disable()
usbhs_disable function was invoking clk_enable() instead of
clk_disable(), thus only increasing the clock usage counter and
preventing this particular clock from being ever turned off.
Because of this, the power domain of omap4 the USB Host subsystem
would never reach lower power states.This patch calls clk_disable()
in usbhs_disable function

Ensure that we never have a window where we've handled an interrupt (and
therefore need to be notified of new events) but haven't yet told the

Jesper Juhl b1224cd113 mfd: Avoid two assignments if failures happen in tps65910_i2c_probe
In drivers/mfd/tps65910.c:tps65910_i2c_probe() there's potential for a
tiny optimization.

We assign to init_data->irq and init_data->irq_base long before we
need them, and there are two potential exits from the function before
they are needed.

Moving the assignments below these two potential exits means we
completely avoid doing them in these two (failure) cases.

Mark Brown 78bb3688ea mfd: Support multiple active WM831x AUXADC conversions
The WM831x AUXADC hardware can schedule multiple conversions at once,
allowing higher performance when more than one source is in use as we
can have the hardware start new conversions without having to wait for
a register write.

Take advantage of this in the interrupt driven case, maintaining a list of
callers that are waiting for AUXADC conversions and completing them all
simultaneously. The external interface of the AUXADC is not changed so
there will be limited use of the feature immediately.

This sleep should not be required on normal circuitry provided the
pull-ups on the bus are correctly adapted to the slaves.  Unfortunately,
this is not always the case.  The sleep is restored but as a parameter to
the probe function in the pdata.

Misael Lopez Cruz f19b2823f8 mfd: twl6040: Add initial support
TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.

TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.

This driver is based on TWL4030 and WM8350 MFD drivers.

Vincent Palatin e6f1945b9e mfd: Fix tps6586x GPIO value setting
In the current code, every time we set a TPS6586x GPIO pin,
the tps6586x_gpio_set function is resetting all other GPIO pins.
We need to update the right GPIOxOUT bit of the GPIOSET2 register instead
of overriding the full value.

Tested by setting sequentially GPIO2 and GPIO3 and verifying the
pins voltage.

This is a snapshot of the current PRCMU firmware API as it looks
right now. The PRCMU firmware is still subject to change. This
also updates the CPUfreq driver to a newer version that will
utilize the new API.

Linus Walleij 650c2a2145 mach-ux500: move the DB8500 PRCMU driver to MFD
We have decided that this function arbiter fits better in the MFD
subsystem. Since we need to concatenate the split header files we move
it basically like this:

mv mach-ux500/prcmu-db8500.c drivers/mfd/db8500-prcmu.c
mv mach-ux500/include/mach/prcmu-defs.h include/linux/mfd/db8500-prcmu.h
mv mach-ux500/include/mach/prcmu-regs.h drivers/mfd/db8500-prcmu-regs.h
mach-ux500/include/mach/prcmu.h >> include/linux/mfd/db8500-prcmu.h
rm arch/arm/mach-ux500/include/mach/prcmu.h

Then we update different #include statements and Makefile orders etc
to make the PRCMU driver compile, link and boot in the new place
without really changing any code.

Axel Lin d11536e4e0 mfd: Fix usbhs_enable error handling
In the case of missing platform_data we do not hold a spin_lock,
thus we should not call spin_unlock_irqrestore in the error path.

Also simplify the error handling by separating the successful path
from error path. I think this change improves readability.

Samuel Ortiz e710d7d5a9 mfd: Fetch cell pointer from platform_device->mfd_cell
In order for MFD drivers to fetch their cell pointer but also their
platform data one, an mfd cell pointer is added to the platform_device
structure.
That allows all MFD sub devices drivers to be MFD agnostic, unless
they really need to access their MFD cell data. Most of them don't,
especially the ones for IPs used by both MFD and non MFD SoCs.

MyungJoo Ham 8de6bc7f6b mfd: Add MAX8997/8966 IRQ control
This patch enables IRQ handling for MAX8997/8966 chips.

Please note that Fuel-Gauge-related IRQs are not implemented in this
initial release. The fuel gauge module in MAX8997 is identical to
MAX17042, which is already in Linux kernel. In order to use the
already-existing MAX17042 driver for fuel gauge module in MAX8997, the
main interrupt handler of MAX8997 should relay related interrupts to
MAX17042 driver. However, in order to do this, we need to modify
MAX17042 driver as well because MAX17042 driver does not have any
interrupt handlers for now. We are not going to implement this in this
initial release as it is not crucial in basic operations of MAX8997.

The cs5535-pms cell doesn't actually need to be cloned, so we can drop that
and simply have the olpc-xo1.c driver use "cs5535-pms" directly.

Also, rename the cs5535-acpi clones to what we actually use for the (currently
out-of-tree) SCI driver.  In the process, that fixes a subtle bug in
olpc-xo1.c which broke powerdown on XO-1s.. olpc-xo1-ac-acpi was a typo, not

Andres Salomon fa1df69168 mfd: Add mfd_clone_cell(), convert cs5535-mfd/olpc-xo1 to it
Replace mfd_shared_platform_driver_register with mfd_clone_cell.  The
former was called by an mfd client, and registered both a platform driver
and device.  The latter is called by an mfd driver, and registers only a
platform device.

The downside of this is that mfd drivers need to be modified whenever
new clients are added that share a cell; the upside is that it fits
Linux's driver model better.  It's also simpler.

This also converts cs5535-mfd/olpc-xo1 from the old API.  cs5535-mfd
now creates the olpc-xo1-{acpi,pms} devices, while olpc-xo1 binds to
them via platform drivers.

rather than doing the swap as part of the I/O operation so move the byte
swaps we're currently doing into the core write function into the register

to the chip.

This leaves reads inconsistent, this will be addressed as a followup patch.

Daniel Willerud 6321992cd3 mfd: Reentrance and revamp ab8500 gpadc fetching interface
This revamps the interface so that AB8500 GPADCs are fetched by
name. Probed GPADCs are added to a list and this list is searched
for a matching GPADC. This makes it possible to have multiple
AB8500 GPADC instances instead of it being a singleton, and
rids the need to keep a GPADC pointer around in the core AB8500
MFD struct.

Currently the match is made to the device name which is by default
numbered from the device instance such as "ab8500-gpadc.0" but
by using the .init_name field of the device a more intiutive
naming for the GPADC blocks can be achieved if desired.

Andres Salomon a9bbba9963 mfd: add platform_device sharing support for mfd
This adds functions to enable platform_device sharing for mfd clients.

Each platform driver (mfd client) that wants to share an mfd_cell's
platform_device uses the mfd_shared_platform_driver_{un,}register()
functions instead of platform_driver_{un,}register().  Along with
registering the platform driver, these also register a new platform
device with the same characteristics as the original cell, but a different
name.  Given an mfd_cell with the name "foo", drivers that want to
share access to its resources can call mfd_shared_platform_driver_register
with platform drivers named (for example) "bar" and "baz".  This
will register two platform devices and drivers named "bar" and "baz"
that share the same cell as the platform device "foo".  The drivers
can then call "foo" cell's enable hooks (or mfd_shared_cell_enable)
to enable resources, and obtain platform resources as they normally
would.

This deals with platform handling only; mfd driver-specific details,
hardware handling, refcounting, etc are all dealt with separately.

Andres Salomon fe891a008f mfd-core: Unconditionally add mfd_cell to every platform_device
Previously, one would set the mfd_cell's platform_data/data_size to point
to the current mfd_cell in order to pass that information along to drivers.

This causes the current mfd_cell to always be available to drivers.  It
also adds a wrapper function for fetching the mfd cell from a platform
device, similar to what originally existed for mfd devices.

Drivers who previously used platform_data for other purposes can still
use it; the difference is that mfd_get_data() must be used to
access it (and the pdata structure is no longer allocated in
mfd_add_devices).

Ensure that the chip is in the lowest power mode possible when suspended
by performing a soft reset on it. On early silicon revisions the lowest
power modes can't be entered without using reset so we can't achieve
equivalent results within the individual drivers.

In OMAP4 Blaze and Panda, 32KHz clock to WLAN is supplied from Phoenix
TWL6030. The 32KHz clock state (ON/OFF) is configured in

MyungJoo Ham 337ce5d1c5 mfd: Support LP3974 RTC
The first releases of LP3974 have a large delay in RTC registers,
which requires 2 seconds of delay after writing to a rtc register
(recommended by National Semiconductor's engineers)
before reading it.

If "rtc_delay" field of the platform data is true, the rtc driver
assumes that such delays are required. Although we have not seen
LP3974s without requiring such delays, we assume that such LP3974s
will be released soon (or they have done so already) and they are
supported by "lp3974" without setting "rtc_delay" at the platform
data.

This patch adds delays with msleep when writing values to RTC registers
if the platform data has rtc_delay set.

Mark Brown 1d83864cab mfd: Remove ARCH_U8500 dependency from AB8500

There appears to be no actual code dependency.
